Leners Patent No. 90,558, dated May 25, 1869.

IMPRovED Sasa-LUCK The Schedule referred to in these Letters Patent andVmaking part of the same.

To all whom it may conce/ru Be it known that I, GEORGE KING, ofFrederick, in the county of Frederick, and State of Maryland, naveinvented a new and useful Improvement in Sash- Locks; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof.

The object oi' my invention is to produce a simple and `convenientsoli-adjusting sash-lock.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation, reference being had,to the accompanying drawings, in which like letters indicate like parts,and in which Figure l represents an upright View of my invention. Y

Figure 2 represents a top'view of the same, taken through the line x.

A A show the uprights of an ordinary sash-frame, on the inside of which,near the top of the frame, the

screws b b are inserted, from which depend the perpendicular rods o c.

B is an ordinary sash, having its opposite sides.

When it is desirable to raise the window, all that is necessary is tothrow the sash up suddenly, so that when it falls back the catches arethrown out of a horizontal line andup against the top of thebevelnotches, which will cause the edges of the' drilled holes in theend of the catches to bind against the rods, and the sash will thus beheld securely in position by its own weight.

To lower the window, raisethe sash slightly and let down gently.

I am aware that a metal dog, pivoted in and extending through the sash,is in use in the patent of W. H. Sible, and therefore do not claim thisarrangement; but

What I 'do claim as new, and desire to secure hy Letters Patent, is-

Loose metal dogs, working upon pendent rods, and resting on the bottomor square of the slot or mortise when the window is descending, alshereinbefore described and set forth.

The above specification of my improvement in sashlocks, signed this 10thday-of March, 1869.

GEORGE KING.
